Abstract
The present invention is an improved sorbent filter for use in both particulate filtration and absorption of gaseous contaminants in a variety of applications, such as for filtration in a computer disk drive. The filter of the present invention provides previously unavailable levels of combined particulate filtration and contaminant sorption while being capable of ready reconditioning (such as through washing with D.I. water).
